I've got one question for this group:
How can i associate the data of one multi ( fx arp bts sends ) to a 
pattern in particular. 
In fact what i want is that: 
When i chain up 2 pattern which are associate to differents multi, i 
want the multi of the second pattern will be remembered automatically 
when i change the pattern.
Is that feature possible?
Thanks
